Value Collection 1524MPF Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 1524MPF is a 1/4-28 unified fine thread flat head Phillips machine screw intended for precision fastening applications across mechanical assembly, HVAC equipment, electrical enclosures, and general fabrication work. The flat head profile sits flush with or below the mating surface, eliminating protrusion in finished assemblies. Manufactured from steel with a zinc finish for basic corrosion resistance, this screw meets ASME B18.6.3 and SAE J82 standards. Overall length is 1-1/2 inches, with length measured from under the head, and the unit weight is approximately 0.0212 pounds per screw. Installation requires a standard Phillips driver or bit.

This machine screw is suited for light industrial, commercial, and residential applications where a flush-mount fastener is needed. Common uses include securing sheet metal panels, control boards, equipment housings, and structural brackets in HVAC systems, electrical enclosures, and plumbing fixture assemblies. The 1/4-28 fine thread provides strong thread engagement in thin or tapped metal sections. This item is sold individually but is subject to a minimum order quantity of 100 pieces, making it appropriate for contractors, technicians, and shops that stock fasteners in bulk.

Installation Notes

Installation is typically performed by a licensed technician or qualified assembler using a Phillips screwdriver or power driver with the appropriate bit size. Ensure the receiving hole is properly tapped to 1/4-28 UNF before driving. Do not overtighten, as fine threads in thin metal can strip under excessive torque. When installing in electrical enclosures, follow NEC guidelines and de-energize the equipment before beginning work.
